Demand Response Programs Definition Using Demand Price Elasticity to Define Consumers Aggregation for an Improved Remuneration Structure

The positioning of the consumers in the power systems operation has been changed in the recent years, namely due to the implementation of competitive electricity markets. Demand response is an opportunity for the consumers’ participation in electricity markets. Smart grids can give an important support for the integration of demand response. The methodology proposed in the present paper aims to create an improved demand response program definition and remuneration scheme for aggregated resources. The consumers are aggregated in a certain number of clusters, each one corresponding to a distinct demand response program, according to the economic impact of the resulting remuneration tariff. The knowledge about the consumers is obtained from its demand price elasticity values. The illustrative case study included in the paper is based on a 218 consumers’ scenario.

European Union emissions trading scheme impact on the Spanish electricity price during phase II and phase III implementation

The European Union Emissions Trading Scheme (EU ETS) is a cornerstone of the European Union's policy to combat climate change and its key tool for reducing industrial greenhouse gas emissions cost-effectively. The purpose of the present work is to evaluate the influence of CO2 opportunity cost on the Spanish wholesale electricity price. Our sample includes all Phase II of the EU ETS and the first year of Phase III implementation, from January 2008 to December 2013. A vector error correction model (VECM) is applied to estimate not only long-run equilibrium relations, but also short-run interactions between the electricity price and the fuel (natural gas and coal) and carbon prices. The four commodities prices are modeled as joint endogenous variables with air temperature and renewable energy as exogenous variables. We found a long-run relationship (cointegration) between electricity price, carbon price, and fuel prices. By estimating the dynamic pass-through of carbon price into electricity price for different periods of our sample, it is possible to observe the weakening of the link between carbon and electricity prices as a result from the collapse on CO2 prices, therefore compromising the efficacy of the system to reach proposed environmental goals. This conclusion is in line with the need to shape new policies within the framework of the EU ETS that prevent excessive low prices for carbon over extended periods of time.

Asymmetric dynamic price competition with uncertainty

We consider a dynamic setting-price duopoly model in which a dominant (leader) firm moves first and a subordinate (follower) firm moves second. We suppose that each firm has two different technologies, and uses one of them according to a certain probability distribution. The use of either one or the other technology affects the unitary production cost. We analyse the effect of the production costs uncertainty on the profits of the firms, for different values of the intercept demand parameters.

The influence of price changes on consumers' purchase decisions

The development of an effective pricing strategy requires the acquaintance of consumers’ price perception as well as the range of elements that influence the price sensitivity. This paper analyses the relationships between product features, individual characteristics and the level of price increase/decrease that induces the consumers to change their purchase decisions. The results of a dedicated survey show, that price sensitivity, individual preferences, type of product and direction of price change and individual characteristics of consumers (gender, age, professional situation) have a significant impact on a threshold at which people are willing to choose the less attractive, but cheaper alternative to their favorite product or give up the variety in consumption. From a consumer behavior perspective, these findings play a fundamental role in pricing.

Measuring the effects of price movements on private consumption

This paper studies how shocks in the prices of Food, Energy and Financial Assets affect private consumption using a VAR Model. Then, the total effects are broken into direct and indirect effects, using the coefficients taken from the previous model. We use quarterly data for the Portuguese economy from the last 20 years. We found that energy prices and financial assets have a strong connection with consumption, suggesting that the economy may be too exposed to shocks in these markets.

The price of honour: The corporate governance of Banco Espirito Santo

The Price of Honour is a case study, supported with teaching notes, which describes the events and circumstances surrounding the implosion of one of Portugal’s most systemically important banks - Banco Espírito Santo (BES). The case focuses on BES’s corporate governance and how the Espírito Santo family’s tight control of the bank led to its exploitation. Although the situation caught the attention of the bank’s supervisors, their untimely actions could not prevent BES’s financial health from crumbling only two months after a rights issue. With little leeway, the supervisors put forward a resolution which dramatically ended the bank’s centennial legacy.

Benjamin Woodruff Price Papers, 1851, 1853-1860, 1862-1863, 1874, n.d.

The fonds includes sixty two items of correspondence between Benjamin Woodruff Price, aka Woodruff, Ben or Uncle, and various family members, both immediate and distant cousins. Also included is business correspondence related to Price’s activities as a watchmaker and/or jeweler. Benjamin Woodruff Price was born in Thorold Township ca. 1831, the son of Joseph Price and Mary Smith. B.W. Price married Ella or Ellen McGlashan (1851-1906) ca. 1868. Price died between 1891 and 1901, his burial location is unknown at present. A watchmaker and jeweler, Price lived most of his life in Fonthill, Ont. He also included auctioneer, undertaker and photographer as some of his other professional activities. His siblings included David Smith Price (wife Isabella Ann), John Smith Price (wife Elizabeth Jane), and sisters Susan Page (husband Edward Rice Page), Jerusha Price, Mary Price and Martha W. Stone (husband Dudley Ward Stone). John Smith Price died 18 April 1860, leaving no descendents. It is likely that G.W. Stone was a nephew to B.W. Price, the son of his sister Martha W. Stone and her husband Dudley Ward Stone. Susan Page was a sister of Benjamin Woodruff Price. She was married to Edward Rice Page and they had at least two children, Joseph and Clayton. At the time of this correspondence they lived in Suspension Bridge, NY, now part of Niagara Falls, New York. Edward Rice Page’s occupation was listed as saloon keeper. The Price family appears to have had a very large extended family. This information was gleaned from the contents of letters of Maggie Tisdale, daughter of Ephraim and Hannah (Price) Tisdale, P.A. or Ann Morgan, [may also be Phebe Ann] of Newark, NY? and Marietta House of Bayham Township. DeWitt Higgins of Suspension Bridge, NY aka Niagara Falls, NY was an auctioneer, specialized in buying jewellery, watches, clocks, from individuals and reselling his product to others like B.W. Price.
